Aspects treat and remove a layer of scale comprising iron oxide and alloying elements oxides that is formed on an advanced high strength metal surface comprising at least two (2) percent by weight of alloy. A first conditioning process compromises structural integrity of or removes iron oxide within the scale layer to expose the alloy oxide to chemical engagement with a disposed aqueous alkali salt solution that is heated to transforming one or more alkali salts within the disposed solution into a quasi-molten form. The alloy oxide is oxidized via reaction with the solution quasi molten alkali salt(s) and water, forming one or more water soluble alkali alloy compounds. A water rinse dissolves and rinses the water soluble compound(s) from the steel product surface of the advanced high strength, leaving a film of iron oxide on the surface that is removed via a final pickling process.

Goods & Services
Chemicals, namely, chemical preparations for the removal of surface scales of iron and alloy oxides formed in the production of high strength carbon steel alloys, and of scales composed of mixtures of iron and alloy oxide formed on metal surfaces with high alloy percentages
Methods and systems are provided for treating oxide scale on the surface of a metal object. In one embodiment, a system temperature control apparatus controls the temperature of metal object's surface to an application temperature below the Leidenfrost temperature point of an alkali metal hydroxide aqueous conditioning solution. An application apparatus wets the metal object's surface at the controlled temperature with a thin layer of the solution that engages the oxide scale, and a heating apparatus heats the wetted surface to a final conditioning temperature above a melting point of the alkali metal hydroxide by an additional value selected to effect conditioning of the oxide scale at a reasonable but not excessive rate by the melting alkali metal hydroxide reacting with the oxide scale. The system terminates additional conditioning to prevent creation of additional oxide scale beyond the conditioned depth.

Salt bath ferritic nitrocarburizing of brake rotors
Ferritic nitrocarburized surface treatment of cast iron brake rotors providing oxidation resistance, good braking performance and absence of distortion. Machined brake rotors are pre-heated, then immersed into a high temperature molten nitrocarburizing salt bath for a first predetermined dwell time. After removing the brake rotors from the nitrocarburizing salt bath, the brake rotors are directly immersed into an oxidizing salt bath at a lower temperature than the nitrocarburizing salt bath so that the brake rotors are thermally quenched. After a predetermined second dwell time in the oxidizing salt bath, the brake rotors are removed therefrom and further cooled to room temperature, either by water application thermal quenching or slow cooling in air. A fixture provides stable holding the brake rotors with a minimum of contact during placement in the salt baths.
